Aside frome spending hundreds to upwards of a thousand dollars to monitor your Alk, this really is the next best thing, to me at least. I was always having trouble trying figure out if the colors were right on other beanded tests in order to make a call, but there's no substitute for having a nice digital readout. Did I save much on the titrations to use, no, did I save time on the guesswork, and shaking, and putting the colors against a lighter background to see whether it was Green, Peach, or Orange...heck yes. Follow the instructions as indicated and it really takes the guesswork away. Not sure why I wated so long to purchase aside from price, but found a great deal here. A must have for the avid reefers.
